Outdoor seating on urban overpasses plays a subtle yet significant role in shaping their microclimate. By altering airflow patterns and providing shade, seating arrangements can reduce surface temperatures by up to 3–5°C, creating localized cooling effects. The strategic placement of benches or plant-integrated seating disrupts wind tunnels common in elevated walkways, improving pedestrian thermal comfort. Materials matter—porous or reflective surfaces on seating further mitigate heat retention, countering the urban heat island effect. Studies show that well-designed seating zones can lower perceived temperatures by enhancing evaporative cooling through adjacent greenery. However, overcrowded seating may inadvertently trap heat, highlighting the need for balanced urban design. These microclimatic adjustments not only enhance usability but also contribute to broader urban sustainability goals.
